Fig. 5. Example of noise barrier anchorage on a bridge: schematic representation (left) and numerical model (right)

Fig. 6 presents the summary results of the anchorage analysis for a post anchored into plain concrete. It is evident that the proposed anchorage does not satisfy the requirements. According to EN 1992-4, the governing failure mode is the pull-out of the concrete cone under tensile loading of the anchor.

Fig. 7. Reinforced concrete anchorage model (left) and equivalent stress distribution (right)

Fig. 7 shows the reinforced concrete block model analyzed using the 3D CSFM. The analysis is performed at the ultimate limit state. The equivalent stress distribution for the governing load case is shown, together with summary results for concrete, reinforcement, and bond stresses. Maximum values are directly compared with design material strengths or allowable bond stresses. Reinforcement stresses can also be visualized, with tensile reinforcement shown in blue and compressive reinforcement in red.
